Senior Java/Kotlin Software Engineer - London

The engineering challenge

Our Software Engineers don't just write code, they solve real financial problems for millions of customers. You'll work on distributed systems processing thousands of transactions daily, build resilient services that handle people's money, and create experiences that make traditionally complex financial products feel simple.

Your impact:

• You love shipping great products, not just writing superb code
• As an Engineer, you’re interested in the problem, not just the requirements
• You feel comfortable in a fast-moving environment and are ambitious about the speed and quality of your code. We ship our code multiple times a week with the impact measured in the result for the customer, not lines of code
• An advocate of test-driven development or, even better, behaviour-driven development. A strong commitment to quality is essential
• You've worked on large scale distributed software systems that have proven scalability and complex topologies
• Enjoy talking to key stakeholders and understand and show passion for the business objectives of the company
• You are comfortable with a fair bit of uncertainty, fast change, and love solving hard problems collaboratively
• You are a team player who thrives working in an honest and friendly working atmosphere. We have a flat hierarchy and give you the opportunity to make a real impact

Your toolkit:

• You'll work with Kotlin, Kafka, Kubernetes, Docker, AWS Aurora Postgres, and other modern technologies. If you haven't worked with all of these, we value skilled engineers with a willingness to learn.
• A product-focused engineering mindset
• Experience building distributed systems at scale
• Test-driven development practices
• Comfort operating in uncertainty and rapid change
• Collaborative problem-solving skills

Our engineering culture:

• Customer impact over unnecessary complexity
• Team success over individual heroics
• Operational ownership, not just feature delivery
• Continuous improvement through honest feedback

Added bonus:

• Experience with fintech or banking is a plus, but we value problem-solvers from all backgrounds
